I just snag the very few standout males as they come, reguardless of strain. By standout, for me, its usually structure, vigorosity(is that even a word, bruh? Lol), and mostly stem rub aroma and strength. But i barely started testing the first one i kept lol. Ill let u know how my selection process is working in a few years hahaha
Edit: forgot the reason i replied lol, i popped a pack of goji but i wasnt feelin any of the 10 males that came from that pack. Which was a bummer cuz i really wanted to f2 the gojis. Id love to find some good goji jiz
